SPECIFICATION forming part of Letters Patent No. 601,200, dated March22, 1898.

Application filed June 21, 1897.

To all whom it may concern.-

Be it known that I, FRANCIS MEISEL, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented an Improvement in- Machines for Cutting Paper from the Webinto Sheets, of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, makingpart of this specification, in which Figure 1 is a side elevation of aportion of a paper-cutting machine embodying my invention. Fig. 2 is aplan of the same, the cutter-head and its gear being removed. Fig. 3 is'an end elevation of the same.

My invention has for its object to provide a paper-cutting machine inwhich a webcan be cut into sheets varying in length by predeterminedfractional parts of inchesthat is to say, the sheet may be cut intostock lengths or the sizes usually carried in stock by paper-dealers;and to this end my invention consists in a machine of this characterembodying certain novel features of construction, whereby the desiredend is accomplished in a more reliable and effective manner thanheretofore.

In the said drawings,A represents the framework of the machine, insuitable bearings in which is journaled the shaft of the roll B, fromwhich is drawn the web 0 of paper to be cut into sheets, said web beingunwound from the roll B by a pair of feed-rolls d e, the shaft 5 of theroll 01 carrying a gear f, which is driven by a train of gears, to behereinafter described, receiving motion from any suitablesource ofpower.

g is a stationary cutter-bladeor knife made adjustablein a stock orsupport 12 by means of a screw i, and it is a rotary cutter-blade orknife cooperating with the stationary knife g and secured to a cylinder0, the axis of which is parallel with the edge of the stationary blade9, the paper being cut into sheets of uniform length as it passesbetween the said cutters.

Tothe shaft of the cylinder 0 is secured a gear 12, which meshes withand is driven by a gear of the same size on a shaft 20, suitablyconnected with the driving-shaft of the machine. I Y

D is a change-wheel which is removably se- Serial No. 641,696. (Nomodel.)

cured to the shaft 20, and this wheel-D meshes with an intermediate gearE, rotating on a stud 'm, mounted on a support 26, swinging on the shaft5 of thelower feed-roll d and held in place when adjusted by aclamping-screw 28, passing through a slot 30, said feed-roll shaftcarrying the gear f, which meshes with the intermediate gear E, wherebymotion is transmitted from the gear 15, which drives the gear 12 andcutter-cylinder O, to the gear f on the shaft 5 of the lower feed-rolld, and thus by'removing the change-Wheel D and substituting another ofdifferent diameter the speed of the feed-rolls with relation to that ofthe cutter-cylinder can be varied as desired to change the length of thesheets cut from the web, and by this construction I am enabled to cutsheets of a great variety of different predetermined lengths,increasing, for instance, by uniform fractional parts of aninch from theshortest to the greatest length, said sheets at the same time havingaclean smooth-edged or non-serrated out.

As shown in the drawings, the gear 12, fastened to the shaft 10 of thecutter-cylinder O, meshes with the gear 15, which is of the samediameter as the gear 12, so that each revolution of the gear 15 producesa single revolution of the cutter-cylinder C and also of the change-gearD, secured to the shaft of said gear 15.

The circumference of the feed-roll dis such that it can be equallydivided into a certain number of quarter-inches. For instance, if thefeed-roll d is twelve inches in circumference it could be divided intoforty-eight longitudinal spaces each a quarter of an inch in length.

The gear f, fixed to the shaft 5 of the roll d, is provided withforty-eight teeth,while the change-gear D is provided with ninety-sixteethu Consequently a single revolution of the gear D will produce,through the intermediate gear E, two complete revolutions of thefeed-roll d, thus feeding forward twenty-four inches of paper. Now if itis desired to feed forward twenty three and three quarter inches ofpaper at each revolution of .the cutter-cylinder C it is merelynecessary to remove the change-gear D and replace it by another gearhaving only ninety-five teeth, and,

onthe other hand, if it should be desired to feed forward a sheettwenty-four and onequarter inches in length the gear D would be replacedby one having ninety-seven teeth, and in this manner the length of thesheet can be increased or diminished by quarters of an inch by theemployment of a change-gear D having the required number of teeththatis, a number of teeth equal to the nu mber of quarters of an inchcontained in the length of the sheet desired to be cut.

It will be obvious from the foregoing that if it should be desired toincrease or diminish the length of the sheets cut by the cylinder C byeighths of an inch instead of by quarters of an inch this can beaccomplished by doubling the number of teeth in each of the wheels f andD, the teeth of the intermediate gear E being made of the proper size tomesh with the teeth of the gears D and f.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. In a paper-cutting machine, the combination with a stationarycutting-knife and a contin uously-rotating cutting-knife, of a pair ofcontinuouslv-rotating feed-rolls, one of said rolls having acircumference divisible into predetermined equal fractional parts ofinches as described, and provided with a gear having a number of teethequal to the said predetermined number of equal fractional parts ofinches contained in the circumference of said feed-roll, said feed-rollgearl meshing with an intermediate gear driven by a change-wheelprovided with the desired number of teeth to actuate the feed-roll atthe required speed with relation to that of the retating cutting-knife,substantially as and for the purpose described.

2. A machine for cutting paper from the Web into stock lengths,comprising a stationary cutting-knife, a continuously-rotatingcutting-knife, a driving-shaft, gears of equal diameter connecting saidshaft With the shaft of the rotary cutter, a pair ofcontinuouslyrotating feed-rolls one of which has its circumferencedivisible into predetermined equal fractional parts of inches, asquarterinches, a gear on the shaft of said roll and having its teethequal in number to the said number of equal fractional parts of inchescontained in the circumference of said feedroll, a change-wheel on saiddriving-shaft and having a number of teeth equal to the number offractional parts of inches, as quarterinches, contained in the length ofthe sheet to be cut, and an adjustable gear connecting the change-gearwith the said feed-roll gear, substantially as described.

\Vitness my hand this 10th day of June, A. D. 1897.
